Cash Purchase
With this method you will pay for the car in full when the car is delivered. You will become the owner of the car when you make the payment. You will benefit from any discounts and special offers at the time of purchase.
One of the problems with cash purchase is that you are restricted (by the money you have available) in your choice and age of the car you can purchase. You should also take into account the cost of using your own money.
For example if you invest your money in a savings account you will have earned interest over a three-year period. Alternatively, you may have other loans or mortgages, which could have been paid off or reduced that may save more than the extra cost of financing the car.
